BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 394,979, dated December 25, 1888.

Application filed July 25, 1888. Serial No. 281,137. (No model.)

To aZZ whom it may concern.-

Be it known that I, GUSTAV HAUT, a citizen of the United States, residing at Perham, in the county of Otter Tail and State of Minnesota, have invented certain new and useful Improvements in Brick-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in brick-machines, and particularly to improvements 011 the machine for which Letters Patent were granted to me on the 13th day of April, 1886, No. 339,881, whereby I am able to construct a simpler and more compact apparatus.

In the annexed drawings, Figure 1 is a perspective view of portions of the improved machine. Fig. 2 is a perspective view of the entire machine with a portion of the casing removed, and Fig. 3 is a perspective view showing various parts separated from the main part of the machine. Fig. at is a detail view showing one of the plunger-rods and adjacent parts.

The main frame A is suitably constructed to support the various parts of the machine. 011 the top of the frame is journaled a driveshaft, B, carrying a bevel-pinion, O, which meshes with a bevel gear-wheel, D, secured on the upper end of an upright shaft, E. This shaft E is stepped in the lower part of the frame A, and there carries a bevel gear-wheel, F, which meshes with another bevel gearwheel, g, loosely mounted on a transverse crank-shaft, II. The shaft II carries cranks on each end, and adjacent to the gear G is provided with a clutch, I, turning with the said shaft and movable longitudinally thereon through the medium of a lever, K, projecting beyond one end of the machine, and there provided with a handle, L, Fig. 2, and at the other end is controlled by a spring, M. The clutch I maybe moved into or out of engagementwith the gear G, and thus start or stop the crank-shaft.

The machine is provided with a carriage, N, which may be constructed in all essential features similar to that shown in the Letters Patent above referred to and therefore is not herein described. The carriage is reciprocated by means of pitmen 0 extending from the cranks on the shaft H to it.

Secured to uprights P of the frame A-one each side of and extending above the carria eare castin s R having slots S in the u per end. (See Figs. 2 and 3.) In these slots are seated the ends of a cross-piece, T, to which is secured a plunger, U. (Shown separately in Fig. 3.) This plunger works in a compressionbox, V, under which the carriage passes carrying molds WV. To the lower end of each casting R is pivoted an angle or bell-crank lever, Y, one arm of which projects downward between the carriage and a guide or bracket, Z, thereon. Near each end of each bracket, and between the same and the carriage, is a roller or stop, A, arranged to engage the said downwardly-projecting arm of the respective lever Y. To the projecting studs of one pair of these rollers A, on the side of the carriage and outside of the bracket, are secured the.

pitmen 0 before mentioned. The other arm of each lever Y is secured to the cross-piece T of the plunger by adjustable spring-connections constructed and controlled as are the connections shown and described in the Letters Patent before referred to. This construction is shown in Fig. 4, one of the spring-surrounded rods being shown at a, and passing through one end of the cross-piece T. The other rod is similarly constructed and passes through the other end of the cross-piece. The rods are provided with sprocket-wheels b at their upper ends connected by chains 0, so that the tension of the springs and the travel of the plunger are regulated simultaneously.

The castings R serve to support the compression-box V and the partitioned guide B used in this class of machines.

The upright shaft E carries a series of stirrers, C, which serve to mix the clay preparatory to its passage to the pressing-box.

In operation, the power being applied, the crank-shaft is caused to revolve, imparting to the carriage a reciprocatory movement. A mold having been placed in position previous to the inward movement of the carriage, it is carried under the compression box, the plunger at this stage of the operation being raised. WVhile the carriage is yet moving, the

' plunger is relieved from the downward press ure and the molds are moved outward. 13etore the carriage completes its outward movement, the other pair of rollers A engages the levers Y and moves them to lift the plunger i preparatory to the depositing of another charge of clay in the box V.

The operation is repeated as often as de- 1 sired, the empty mold being each time substituted for the filled one.

As it is evident that modifications of the invention would be readily suggested to a skilled mechanic by the foregoing description I and the drawings, I do not contine myself to the exact construction and arrangement of parts described and shown.

Having described my invention, what I claim isl E i 1. In a brick-machine, a reciprocating carriage carrying the mold-box, a plunger moving at an angle to the movement of the carriage, and. angle-levers connected to the plunger and operated by the carriage, substantially as specified.

In a brick-machine, a reciprocating carriage tor the mold-box, and provided at the sides with guides and stops, a plunger t'or compressing the clay, and angle-levers connected to the plunger extending into the guides at the sides of the carriage and operated by the said stops, substantially as specified.

In testimony whereof I aiiix my signature in presence of two witnesses.
